Abstract
Abstract The grapevine cultivated in tropical regions, such as the Sub-medium of the São Francisco Valley, exhibits a strong bud dormancy and high apical dominance, thus presenting the need for the utilization of products that promote the dormancy breaking of the buds. The aim of the present work was to evaluate the efficiency of the application of hydrogenated cyanamide and the practice of cane torsion over the breaking of bud dormancy, bud burst and yield of grapevine cv. Italia Muscat in the conditions of the Sub-medium of the São Francisco Valley. The experiment was conducted in Petrolina, PE state, during two production cycles (2015-2016). The adopted design was in randomized blocks, with treatments distributed in a 2 x 2 factorial scheme, referring to the torsion of canes (with and without) and the different doses [D1: hydrogenated cyanamide (H2CN2) 2.45%; D2: hydrogenated cyanamide (H2CN2) 2.94%], with four replicates. The use of the hydrogenated cyanamide associated to the torsion of canes influences in a distinct manner the studied variables, in the different production cycles, although increments in production and yield occur in both. Therefore, the use of 2.94% of H2CN2 along with the torsion of canes is a recommended practice for the increase in the bud burst rate and yield of grapevine cv. Italia Muscat, cultivated in the region of the Sub-medium of the São Francisco Valley.
